　　The simple act of surrendering a telephone number to a store clerk may not seem harmful--so much so that many consumers do it with no questions asked. Yet that one action can set in motion a cascade of silent events, as that data point is acquired, analyzed, categorized, stored and sold over and over again. Future attacks on your privacy may come from anywhere, from anyone with money to purchase that phone number you surrendered. If you doubt the multiplier effect, consider your e-mail inbox.

But privacy issues don’t necessarily involve large faceless institutions: A spouse takes a casual glance at her husbands Blackberry, a co-worker looks at e-mall over your shoulder or a friend glances at a cell phone text message from the next seat on the bus. while very little of this is news to anyone--people are now well aware there are video cameras and Internet cookies everywhere--there is abundant evidence that people live their lives ignorant of the monitoring, assuming a mythical level of privacy. People write e-mails and type instant messages they never expect anyone to see. Just ask Mark Foley or even Bill Gates, whose e-mails were a cornerstone of the Justice Departments antitrust case against Microsoft.
　　And polls and studies have repeatedly shown that Americans are indifferent to privacy concerns. The general defense for such indifference is summed up a single phrase:
